Patrick Rhone and I will spend Friday morning talking micro blogs at CoCo Coworking in St. Paul. (Get the event details here.) Patrick is a Tumblr aficionado; I evangelize Posterous. The plan is to for one of us to bring up a feature from our favorite tool and describe it then the other one of us will respond with how their blog does it better, different, worse, or not at all. We'll alternate on who initiates the feature descriptions.After we are done with that portion of the show, Patrick and I will hang out to answer questions and help you get an account going on Posterous (which will likely dominate) or Tumblr. Join us! The deal includes breakfast.
